FRANK KESSLER, SR., OF MILWAUKEE, WISCONSIN.

s'rovE on RANGE.

To all whom it may concern Be it known that I, FRANK KESSLER, Sr., a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Stoves or Ranges, of which the following is a description, reference being bad to the accompanying drawings, which are a part of this specification.

This invention relates to certainnew and useful improvements in cooking stoves or ranges and has for one of its objects to provide a shiftable or adj ustable fire box whereby the heat may be shifted from one end of the stove to another. 7

Another object of this invention is to provide an improved form of fire box in which the sides are made of readily removable steel plates of light weight and durable construction.

A further object of this invention is to provide an improved grate construction of spaced apart steel bars whereby burning out of the grate is practically eliminated.

A still furtheriobject of this invention is to provide a cooking stove or range having a shiftable firebox and means for prevent ing the communication of the fire box'space with the heating space thereabove irrespec' tive of the position of the fire box.

With the above and other objects in View which will appear as the description pro ceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it beingunderstood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawings I have "illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a front view of a cooking stove or range embodying my invention.

Fig. 2 is a sectional view taken trans- Specifieation of Letters l atent. Patented Sept. 27, 1921.

1920. Serial No. 383,508.

y ersely therethrough on the line 22 of Fig. 3 is an enlarged fragmentary sectional view taken on the plane indicated by the line 3-3 of Fig. 2; and

Fig. 4 is a fragmentary sectional view taken at right angles with respect to Fig. 3 (1)31 the plane indicated by the line 4-4 of Feferring now more particularly to the accompanying drawings my invention may be said to consist broadly of an inclosing supporting frame 5 open at its top and provided with a removable cover 6 in which are removably mounted plates 7 The frame 5 has its interior divided into two chambers orcompartments 8 and 9 forming a fire box receiving space and a top heating compartment, respectively.

The twocompartments 8 and 9 are divided by partitions 10 and 11 to be later described.

Fixed to the inner walls of the front and rear sides of theframe 8 near the top thereof are angle plates 12 forming track members from which thefire' box is slidably suspended within the fire box space 8. The fire box consists of an upper rectangular frame 13 and a lower rectangularframe 14 retained in spaced relation by end plates 15, the end plates having their upper ends projected above'the fire box proper and then directed laterally and downwardly as at 16 over the angle plates 12 and having roller members 17 journaled therein and tracking upon said angle plates. I

The lower frame 14 is formedby two opposed sectionsof angle. irons providing a rectangular channel 18 for receiving the lowerv edges of the'side and end fire box walls 19 which have angle irons 20 secured thereto, adjacent their uppermost edges, for engagement with the top of the upper frame 13'. The wall sections 19 are readily removable and the side walls are formed of a high quality sheet steel reinforced against buckling by channel pieces 21 secured to the outer face thereof, and the end walls are also formed of a, high quality sheet steel but are not provided with the channel pieces as the area of the same is not so great as to be in danger of buckling from heat. The end walls are also further secured in place by means of angle plates 22 secured adjacent the ends of the side walls forming, with the plate 15, a channel or guide in which the side edges of the end walls are positioned An ash pit 23 within which is removably positioned a pan 24 is disposed beneath the fire box and formed by an end wall 25 carried by the frame 18 and a frame work 26 formed in part by the wall 25 and further supported from the frame 13 by brace rods 27 As is usual, the supporting frame 5 is provided with an opening leading into the fire box and another leading into the ash pit when the same are in their normal positions, which openings are closed by doors 28 and 29, respectively.

The heating chamber 9 has an extension 30 leading therefrom which is in communlcation with a flue 31, and I provide means for moving the fire box toward and away from said flue to shift the heating surface of the cover 6 or to increase or decrease the heat sent through the flue 81 when the same is connected with an oven. The means for moving the fire box consists of a shaft 32 journaled transversely within the frame 5 adjacent the extension 30 and having a hand crank 33 secured to the outer end thereof for rotating the same. As depicted in Figs. 1 and 2, the handle 33 has a pivotal connection with the shaft 82 whereby the same may be positioned against the side of the frame 5 when not in use.

Secured to the shaft 32 adjacent the opposite walls of the frame 5 are two gear pinions 84 which are in mesh with the teeth of gear racks 85 having their inner ends pivotally connected as at 36 with the upper adjacent ends of the plates 15. From this construction it will be readily seen that if the crank 33, and consequently shaft 32, is rotated in a clockwise direction, with reference to Fig. 1, the fire box will be moved nearer to the flue 31. WVhen the shaft isrotated in a counter clockwise direction the fire box will be moved away from the flue to the position depicted in Fig. 3.

The partition 10 is carried by the fire box, as best shown in Fig. 8, and has its end distant from the fire box slidable over the bot- -tom of extension 30 so that irrespective of the position of the fire box the portion of the fire box chamber 8 between the fire box and extension will be at all times shut off from communication with the heating chamber 9. The partition 11 is in two sections 37 and 38 having their inner ends hingedly connected as at 39 and their outer ends hingedly con- I nected with the adjacent side of the frame 5, as at 40 and to the adjacent side of the frame 13 as at 41, respectively.

From this construction it will be apparent that when the fire box is in the position depicted in Fig. 3, the partition 11 will be folded and when the fire box is moved toward the flue 31, the partition 11 will extend and at all times prevent the communication between the adjacent portions of the compartments 8 and 9.

The bottom of the fire box proper is closed by an improved form of grate including two sections each consisting of an outer pivot bar 42 pivotally mounted in the lower frame 14 near the adjacent side thereof and having secured thereto a plurality of spaced grate bars 43 of a high grade of steel. The bars 43 are secured to the pivot bar 42 by means of transverse bolts or rods 44 and upon which the bars 48 are held in spaced relation by the means of spacing members 45. As best shown in Fig. 3, the grate sections normally tend to drop but are held in horizontal position by means of a yoke 01" crank 46 formed in the inner end of a shaker rod 47, which inner end is journally suspended beneath the grate by means of supports 48.

The grate sections rest upon the yoke 46 and the movement of the yoke or crank is limited by two brackets 48 carried by the grate sections, and when thegrate sections are in their normal horizontal positions, the crank 46 will engage against the adjacent side of the brackets 48 and be slightly to one side of an imaginary line drawn perpendicular to the shaft 47. When it is desired to shake the grate, the shaft 47 is oscillated, and to dump the grate the crank 46 is moved toward the side 49 of the brackets 48 which'will permit the grate sectrons to drop to substantially vertical posi- The shaft 47 passes through an aperture 50 within the plate 25 and has its outer end provided with a crank 51, exteriorly of the frame 5 for convenience in operating the same. A stop 52 is normally provided to limit the oscillation of the handle 51 to prevent the dumping of the grate, but when it is desired to dump the grate the stop 52 may be readily moved out of the path of the handle. I i

From the foregoing description taken in connectlon with the accompanying drawings it will be readily apparent to those' the communication of the heat compartment with the top of the fire box chamber irrespective of the position of said fire box.

2. A stove comprising an inclosing frame having a top heat compartment and a fire box chamber, a fire box movably mounted within said chamber, and means preventing the communication of the heat compartment with the top of the fire box chamber irrespective of the position of said box, said 10 means including a plurality of hingedly connected plates, the outermost of said plates being pivotally connected with the inclosing frame and the innermost of said plates being pivotally connected with the adjacent side of 15 the movable fire box.

I testimony whereof I afiix my signature.
